I posted this on the 1 forums but figured I'd give it a shot on the e90 forums aswell since our cars are very similar.

Long story short I purchased a 135i from Florida. Florida emissions is different than Oregon. The ECU on my 135i is from a 335i. The ECU/DME's VIN is not identical to the VIN on my 135i's body so it will not pass DEQ/Emissions.

I ran a carfax on the VIN that is on the DME/ECU, and the car is not stolen etc.. It's actually located in New York and is still being driven to this day(odd that they sold the DME off).

I'm almost certain that whoever had this 135i before me bought a new DME, CAS, and FOB(matching), or else it wouldn't have been able to run without bypassing or emulating a lot of different things on the DME/CAS.

My question is in regards to changing the VIN in the DME/ECU to match the VIN on the chassis of the car.

By changing the VIN on my DME/ECU will I need to purchase a new CAS/FOB? Or since the CAS was already programmed will the car still start/run once I simply input a new VIN on the DME?

If the VIN on the CAS is different from the VIN(new) that I'll be changing the DME to, will I need to buy a new CAS and FOB, or is there a way to remove the CAS/FOB and have it reprogrammed to synchronize with the DME's VIN.



Crazy situation that I somehow ended up in, but I know someone has gone through something similar considering how many used DME's are on the market.

This is not really a stereo board question.

Thought this board was for all electronic related questions lol. I sent him a message we'll see what they have to say about it. Thanks for the lead.
